Step-by-step explanation:
1/ 3 is the probability of getting one head
Let's rewrite the given expression correctly:
(2y3 + 3y2 - 4y - 5) / (y + 1)
Dividing the expression between y + 1 we have:
2y2 + y - 5
We can check the result:
(2y2 + y - 5) * (y + 1)
= (2y3 + y2 - 5y + 2y2 + y - 5)
= (2y3 + 3y2 - 4y - 5)
Division OK.
Answer:
The result of the division is:
2y2 + y - 5
Yeah he his incorrect because t=subsequently
Cost = $15 + $ .18x
y = .18 (40) + 15
y = 7.2 + 15
y = 22.2
so the answer is $22.20
check:
22.20 = .18x + 15
7.2 = .18x
x = 40
